■^2 FUNGUS-FLOEA. 



thin, fibrillose root. Pileus membranaceous, conico-oonvox 

 when young, then plane, centre depressed, umbo brown, rest 

 pallid or whitish, variegated with brown lines, 2-4 lines 

 Ijroad, glabrous, sometimes pruinose. Gills adnate at first, 

 then deeply decurrent owing to the depression of the pileu^, 

 -distant, alternate ones shorter, clear while. More closely 

 -allied to the Pilopedes section of Mycena than to Omphalia, 

 although from the deeply decurrent gills might be placed in 

 'Omphalia. (Fries.) 



Mycena coUariata. Fr. 



Pileus J-f in. across, membranaceous; campanulate then 

 oonvex, somewhat umbonate, striate, brownish or greyish- 

 white with a brownish disc, becoming pale, glabrous ; gills 

 adnate to a collar round the stem, narrow, crowded, distinct, 

 whitish or with a tinge of flesh-colour; stem about 1^- in. 

 long, ^ line and more thick, tough, glabrous, shining, pale. 



Agaricus (Mycena) collariatus. Pries, Obs., ii. p. 164; Cke., 

 Hdbk., p. 86; Cke., Illustr., pi. 189c. 



Among grass in woods, &c. 



Distinguished by the gills separating from the stem and 

 attached to each other behind as if by a collar. 



Stem about 1 in. long and nearly 1 line thick, slightly 

 striate under a lens. Pileus ^ in. and more broad, typically 

 fuscous, but often greyish-white with a brownish disc ; gills 

 rather distant when the pileus expands. Allied to Mycena 

 Mannem, which differs in the firmer stem. The collar is not 

 free, as in Marasmius rotula, but the gills are joined behind, 

 ^nd cohere to the stem, and at length secede. (Pries.) 



Mycena vitilis, Fr. 



Pileus 3-4 lines across, membranaceous ; conical then ex- 

 panded, papillate, deeply striate when moist, brownish or 

 greyish-white, becoming pale ; gills narrowed behind and 

 A^dnate, rather distant, greyish-white ; stem 3-6 in. long, 

 very slender, equal, slightly bending under the weight of 

 -the pileus, glabrous, juiceless, shining, rooting. 



Agaricus (Mycena) w'tiZis, Fries, Epicr., p. 113; Cke., Hdbk., 

 p. 85; Cke., Illustr., pi. 189b. 



Among leaves in damp places. 



Distinguished by the very long, slender, weak stem and 

 sdeeply striate pileus.
